Report: No endangered animals in 200 zoos across the US!

May 17, 2015 / / 0 Comments




Excerpt from thenextdigit.com

On May 15, the 10th anniversary of Endangered Species Day has been kicked off across the United States, which sees a series of wildlife awareness events with the participation of over 200 zoos. These zoos across the country restricted access to a few of their endangered animals and birds to make visitors feel the non existence of such species.
Ohio’s Akron Zoo also participated in the awareness event, where it shrouded Sumatran tigers from visitors, with only limited access to visitors to capture a glimpse of the endangered tiger species. In Dallas Zoo, authorities kept the African penguins were kept away from visitors’ sight, while allowing those visitors who commit to eat sustainable seafood, switching off lights when not in use and such kind of conservation efforts.

Ohio’s Akron Zoo’s director of marketing and guest services David Barnhardt revealed that the zoo will be using this event to launch their own program SAFE (Saving Animals from Extinction) where the zoo will create awareness of saving endangered animals. SAFE is sponsored by the Association of Zoos and Aquariums. He also said,
“Through SAFE we will pull all of these resources we have available to us and develop action plans, raise awareness and engage the public to help these endangered species.”
Endangered Species Day is an opportunity for every humans to learn about the importance of animals, especially endangered species, and day to day actions they can take to protect these species, according to the Endangered Species Coalition. The Endangered Coalition not only sponsors events in the states, but also provides toolkits for zoos which interested in its own endangered species awareness programs such as SAFE.
Dallas Zoo has initiated a program in February 2015, named as the Wild Earth Academy, which educates people about endangered species. Ben Jones, Wild Earth Academy’s Senior Director and Dean, said in a statement:
“There’s a balance in nature and it’s very evident that that balance is becoming imbalanced, it’s shifting. We have to do our part to use the resources that we have, but not use them up.”
The Coalition also produces the yearly report “Vanishing: Ten American Species Our Children May Never See” – listing the top 10 most endangered species during the time of reporting. 2014’s ‘Vanishing’ report listed endangered animals like the Monarch butterfly, Mountain yellow-legged frog (extinct from southern Sierra Nevada), North Pacific right whale, great white shark (California/Mexico), little brown bat (extinct due to white-nose syndrome, an illness caused by a deadly fungus from Europe), whitebark pine, rusty patched bumblebee, greater sage-grouse, polar bear and snake river sockeye salmon.

Shortest Total Lunar Eclipse of the Century Visible Early Saturday

April 3, 2015 / / 0 Comments


 


Excerpt from space.com 
By Calia Cofield 

Don't forget to look skyward in the early hours of Saturday morning (April 4), to catch a glimpse of the shortest total lunar eclipse of the century.

The moon will be completely swallowed by Earth's shadow for just 4 minutes and 43 seconds on Saturday morning, according to NASA officials. During that time, the moon may change from its normal grayish hue to a deep, blood red. The total eclipse begins at 6:16 a.m. EDT (1016 GMT). You can watch a live webcast of the eclipse on the Slooh Observatory website, Slooh.com, or here at Space.com courtesy of Slooh, starting at 6 a.m. EDT (1000 GMT).
That color change can make for a dramatic display, especially for humans in the distant past, NASA officials said. 


"For early humans, [a lunar eclipse] was a time when they were concerned that life might end, because the moon became blood red and the light that the moon provided at night might have been taken away permanently," Mitzi Adams, an astronomer at NASA's Marshall Space Flight Center in Huntsville, Alabama, said during a news conference today (April 3). "But fortunately, [the light] always returned." 

The April 4 eclipse is the third in a series of four total lunar eclipses — known as a lunar tetrad — visible in the United States. Each of the eclipses is separated by about 6 months. The final installment of this four-eclipse series will occur on Sept. 28. Saturday's lunar eclipse follows closely behind the total solar eclipse that took place on March 20.

Earth's shadow has an outer ring, called the penumbra, and an inner core, called the umbra. Where the moon passes into the penumbra, it appears dark, as if a bite had been taken out of it. When the moon passes though the umbra, it turns a deep, red color.

A total lunar eclipse occurs when the moon is totally submerged in the umbra. On Saturday, the moon will begin to enter the umbra at about 6:16 a.m. EDT (1016 GMT) but will not be completely covered by the shadow until about 7:57 EDT (1157 GMT), after the moon has set in most locations east of the Mississippi River.

While the total eclipse will last less than five minutes, the moon will be partially submerged in the umbra for about one hour and 40 minutes. The dark shadow of the penumbra will first be visible on the moon's surface starting at about 5:35 a.m. EDT (0935 GMT), according to Sky and Telescope magazine.

Viewers west of the Mississippi River will be able to see the total lunar eclipse, starting at about 4:57 a.m. PDT (1157 GMT). Skywatchers in Hawaii and western Alaska will be able to watch the entire eclipse, from the moon's entrance to its exit from the penumbra.

Viewing Guide for Total Lunar Eclipse, April 4, 2015
This world maps shows the regions where the April 4 total lunar eclipse will be visible. The best viewing locations are in the Pacific Ocean.

This weekend's eclipse is extremely short because the moon is only passing through the outskirts of the umbra. (The shortest total lunar eclipse in recorded history, according to Adams, was in 1529 and lasted only 1 minute and 41 seconds).

The eclipse will not be visible in Europe or most of Africa. The partial eclipse will be visible in all except the easternmost parts of South America. The best viewing locations for the total eclipse will be in the Pacific region, including eastern Australia, New Zealand and other parts of Oceania.

This Alien Color Catalog May Help Us Spot Life on Other Planets

March 16, 2015 / / 0 Comments






Excerpt from smithsonianmag.com


In the hunt for alien life, our first glimpse of extraterrestrials may be in the rainbow of colors seen coming from the surface of an exoplanet.

That's the deceptively simple idea behind a study led by Siddharth Hegde at the Max Planck Institute for Astronomy in Germany. Seen from light-years away, plants on Earth give our planet a distinctive hue in the near-infrared, a phenomenon called red edge. That's because the chlorophyll in plants absorbs most visible light waves but starts to become transparent to wavelengths on the redder end of the spectrum. An extraterrestrial looking at Earth through a telescope could match this reflected color with the presence of oxygen in our atmosphere and conclude there is life here.


exoplanets palette
Eight of the 137 microorganism samples used to measure biosignatures for the catalog of reflection signatures of Earth life forms. In each panel, the top is a regular photograph of the sample and the bottom is a micrograph, a version of the top image zoomed-in 400 times.



Plants, though, have only been around for 500 million years—a relative blip in our planet's 4.6-billion-year history. Microbes dominated the scene for some 2.5 billion years in the past, and some studies suggest they will rule the Earth again for much of its future. So Hegde and his team gathered 137 species of microorganisms that all have different pigments and that reflect light in specific ways. By building up a library of the microbes' reflectance spectra—the types of colors those microscopic critters reflect from a distance—scientists examining the light from habitable exoplanets can have a plethora of possible signals to search for, the team argues this week in the Proceedings of the National Academy of Sciences.

"No one had looked at the wide range of diverse life on Earth and asked how we could potentially spot such life on other planets, and include life from extreme environments on Earth that could be the 'norm' on other planets," Lisa Kaltenegger, a co-author on the study, says via email. "You can use it to model an Earth that is different and has different widespread biota and look how it would appear to our telescopes."

To make sure they got enough diversity, the researchers looked at temperate-dwelling microbes as well as creatures that live in extreme environments like deserts, mineral springs, hydrothermal vents or volcanically active areas.

While it might seem that alien life could take a huge variety of forms—for instance, something like the silicon-based Horta from Star Trek—it's possible to narrow things down if we restrict the search to life as we know it. First, any life-form that is carbon-based and uses water as a solvent isn't going to like the short wavelengths of light far in the ultraviolet, because this high-energy UV can damage organic molecules. At the other end of the spectrum, any molecule that alien plants (or their analogues) use to photosynthesize won't be picking up light that's too far into the infrared, because there's not enough energy at those longer wavelengths.

In addition, far-infrared light is hard to see through an Earth-like atmosphere because the gases block a lot of these waves, and whatever heat the planet emits will drown out any signal from surface life. That means the researchers restricted their library to the reflected colors we can see when looking at wavelengths in the visible part of the spectrum, the longest wavelength UV and short-wave infrared.

The library won't be much use if we can't see the planets' surfaces in the first place, and that's where the next generation of telescopes comes in, Kaltenegger says. The James Webb Space Telescope, scheduled for launch in 2018, should be able to see the spectra of relatively small exoplanet atmospheres and help scientists work out their chemical compositions, but it won't be able to see any reflected spectra from material at the surface. Luckily, there are other planned telescopes that should be able to do the job. The European Extremely Large Telescope, a 40-meter instrument in Chile, will be complete by 2022. And NASA's Wide Field Infrared Survey Telescope, which is funded and in its design stages, should be up and running by the mid-2020s.

Another issue is whether natural geologic or chemical processes could look like life and create a false signal. So far the pigments from life-forms look a lot different from those reflected by minerals, but the team hasn't examined all the possibilities either, says Kaltenegger. They hope to do more testing in the future as they build up the digital library, which is now online and free for anyone to explore at biosignatures.astro.cornell.edu.

Warp in spacetime lets astronomers watch the same star explode four times

March 8, 2015 / / 0 Comments



Excerpt from csmonitor.com

Thanks to a phenomenon known as gravitational lensing, the Hubble Space Telescope has captured four images of the same supernova explosion.

For the first time, a cosmic magnifying glass has allowed scientists to see the same star explosion four times, possibly offering a revealing glimpse into these explosive stellar deaths and the nature of the accelerating universe.

Astronomers using the Hubble Space Telescope have captured four images of a supernova explosion in deep space thanks to a galaxy located between Earth and the massive star explosion. You can see how Hubble saw the supernova in this NASA video. The galaxy cluster warped the fabric of space and time around it — like a bowling ball placed on a bed sheet — allowing scientists to see the supernova in four images.

"It was predicted 50 years ago that a supernova could be gravitationally lensed like this, but it's taken a long time for someone to find an example," lead study author Patrick Kelly, an astronomer at the University of California, Berkeley told Space.com. "It's fun to have been able to find the first one." 

The supernova, which was discovered on Nov. 11, 2014, is located about 9.3 billion light-years away from Earth, near the edge of the observable universe. The researchers have named the distant supernova SN Refsdal in honor of the late Norwegian astrophysicist Sjur Refsdal, a pioneer of gravitational lensing studies. Due to gravitational lensing, "the supernova appears 20 times brighter than its normal brightness," study co-author Jens Hjorth, head of the Dark Cosmology Centre at the Niels Bohr Institute at the University of Copenhagen, said in a statement.
The lensing galaxy, which is about 5 billion light-years from Earth, is part of a large cluster of galaxies known MACS J1149.6+2223. In 2009, astronomers discovered that this cluster was the source of the largest known image of a spiral galaxy ever seen through a gravitational lens.

The four images of the supernova each appeared separately over the course of a few weeks. This is because light can take various paths around and through a gravitational lens, arriving at Earth at different times.

Using gravity as a lens

Gravity is created when matter warps the fabric of reality. The greater the mass of an object, the more space-time curves around that object and the stronger its gravitational pull, the discovery enshrined in Einstein's theory of general relativity, which celebrates its centennial this year.

As a result, gravity can also bend light like a lens, meaning objects see n behind powerful gravitational fields, such as those of massive galaxies, are magnified. Gravitational lensing was first discovered in 1979, and today gravitational lenses can help astronomers see features otherwise too distant and faint to detect with even the largest telescopes.

"These gravitational lenses are like a natural magnifying glass. It's like having a much bigger telescope," Kelly said in a statement. "We can get magnifications of up to 100 times by looking through these galaxy clusters."

When light is far from a gravitationally lensing mass, or if the gravitationally lensing mass is not especially large, only "weak lensing" occurs, barely distorting the light. However, when the light comes from almost exactly behind the gravitationally lensing mass, "strong lensing" can happen. 

When a strongly lensed object occupies a large patch of space — for instance, if it's a galaxy — it can get smeared into an "Einstein ring" surrounding a gravitationally lensing mass. However, strong lensing of small, pointlike items — for instance, super-bright objects known as quasars — often produces multiple images surrounding the gravitationally lensing mass, resulting in a so-called "Einstein cross."

The observations of SN Refsdal mark the first time astronomers on Earth have witnessed strong lensing of a  supernova, with four images of an exploding star arrayed as an Einstein cross.

An expanding universe

These new findings could help scientists measure the accelerating rate at which the universe is expanding, researchers say.

A computer model of the lensing cluster suggests the scientists missed chances to see the lensed supernova 50 and 10 years ago. However, the model also suggests more images of the explosion will repeat again within the next 10 years.

The timing of when all these images of the supernova arrive depends on the gravitational pull of the matter generating the gravitational lens. So, by measuring those times, the researchers hope to map how visible normal matter and invisible dark matter is distributed in the lensing galaxy.

Dark matter is currently one of the greatest mysteries in science, a poorly understood substance thought to make up five-sixths of all matter in the universe. A better understanding of how dark matter is behaving in this gravitationally lensing cluster might help shed light on the material's nature, Kelly said.

Analyzing when the images arrive could also help scientists pinpoint the rate at which the universe is expanding. Although there are already several ways to measure the cosmic expansion rate, "there has been a lot of heated debate between different methods, so it'd be interesting to see how this new technique might affect the area," Kelly said. "It's always nice to have completely independent measurements of the same quantity."

The scientists detailed their findings in the March 6 issue of the journal Science.

February 21, 2015 / / 0 Comments
Published on Dec 5, 2014

Wanderers is a vision of humanity’s expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available.
Without any apparent story, other than what you may fill in by yourself, the idea of the film is primarily to show a glimpse of the fantastic and beautiful nature that surrounds us on our neighboring worlds – and above all, how it might appear to us if we were there.

10 Mysterious Biblical Figures No One Can Explain

February 3, 2015 / / 0 Comments






listverse.com

The canonical Bible is filled with mysterious characters, many of whom drop in for a cameo, do their thing, and then slide out, never to be heard from again. Some are merely extras, but some have a contextual presence that begs further examination. And some are, well, just weird.

10  Melchizedek

01
 
Probably the single most mysterious figure in the Bible, Melchizedek was a priest-king of Salem (later known as Jerusalem) in the time of Abram (Abraham), suggesting a religious organization, complete with ritual and hierarchy, that predated the Jewish nation and their priestly lineage from the tribe of Levi. He is only portrayed as active in one passage, although he is alluded to once in Psalms, and several times in the New Testament’s Epistle to the Hebrews.
Some Jewish disciplines insist that Melchizedek was Shem, Noah’s son. He is thought of, in Christian circles, as a proto-messiah, embodying certain traits later given to Christ. New Testament writings assert that Christ was “a priest forever in the order of Melchizedek,” indicating an older and deeper covenant with God than the Abrahamic-Levite lineage.
Hebrews 7, though presents him in a more unusual light. In verses 3 and 4:
“Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually. Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils.”
Not only do these verses grant Melchizedek a hierarchical level above the most important Jewish patriarch, they assign him mystical qualities. Some take this to mean an earlier incarnation of Christ. Others see it as an ancient manifestation of the Holy Spirit. His identity, role, and theological function have long been debated.
The paucity of scriptural references have added to the mystery, making him a somewhat spectral figure. As such, newer spiritual traditions, as well as New Age quacks, have taken liberties with his persona. Gnostics insisted he became Jesus, and he is cited as a high-level priest in Masonic and Rosicrucian lore. Joseph Smith wrote that he was the greatest of all prophets, and Mormons still trace their priesthood back to him. The Urantia, a 20th-century pseudo-Bible that claims to merge religion, philosophy, and science, insists he’s the first in an evolutionary succession of deification manifestations, with Abraham being his first convert.
There is even a school of thought that Melchizedek is a title or assumed character name, sort of a theological 007, played by a series of Judeo-Christian James Bonds. 

The lore of Melchizedek is confusing but deep and fascinating. Apocryphal books give us more details, some cryptic, some relatively mundane. The Second Book of Enoch is particularly informative, insisting Melchizedek was born of a Virgin. When his mother Sophonim (the wife of Noah’s brother Nir) died in childbirth, he sat up, clothed himself, and sat beside her corpse, praying and preaching. After 40 days, he was taken by an archangel to the Garden of Eden, protected by angels and avoiding the Great Flood without passage on Uncle Noah’s ark.

9  Cain’s Wife

02
 
Cain was, according to Genesis, the first human ever born. He later killed his younger brother Abel in a hissy fit over his sacrifice of meat being more favored than Cain’s sacrificial fruit basket. God put a mark on Cain and cursed the ground he farmed, forcing him into a life as a wandering fugitive. 

That part of the story is fairly well known. Later, though, we read that he settled in the Land of Nod, and, all of a sudden, he has a wife. Absolutely nothing else is mentioned about her. We don’t even know where she came from. In fact, the question of where Cain got his wife, when his immediate family were apparently the only people in the world, has sent many a perceptive young Sunday schooler down the road of skepticism. 

Some have posited a mysterious other tribe of people, maybe created after Adam and Eve, maybe even another race or species. But the standard response is that Adam and Eve had many other sons and daughters to populate the Earth. The only way to keep the human race going would be to mate with siblings, nieces, nephews, and cousins. 

In fact, though the Holy Bible is silent on her identity, the apocryphal Book of Jubilees tells us exactly who was Cain’s wife: his sister Awan, who bore his son Enoch.

8  Joseph Barsabbas

03
 
After Judas Iscariot turned in his resignation by selling out his boss, Jesus’s disciples rushed to fill the open position and bring the number back up to a more theologically apt 12. The remaining disciples, including the newly convinced Thomas, looked over the candidates from the 120 or so adherents who followed Jesus. Then they cast lots to pick who would fill the position. 

It went to Matthias, a fairly mysterious character himself. We don’t know where he came from or his previous occupation. Some think he was actually the diminutive Zacchaeus, the tax collector who climbed a sycamore tree to get a better glimpse of Jesus’s ride on the donkey.
The man who lost out was Joseph Barsabbas, also known as Joseph Justus. We know nothing solid about him, even less than we know about Matthias.
There is, however, one bit of interesting speculation. A list of names presented in Mark 6:3 includes some of Christ’s earliest and most loyal adherents. One of these is a man named Joses, and another is James the Just. Biblical scholar Robert Eisenman suggests that James carried on Jesus’s work, and the writer of the Book of Acts assigned him an alias to minimize his importance.

7  The Beloved Disciple

04
 
In the Gospel of John, several references are made to “the disciple whom Jesus loved.” This particular favorite is present at the Last Supper, the crucifixion, and after the resurrection. The writer of the Gospel of John even states that the testimony of this disciple is the basis for the text. But there is considerable debate over the identity of this mystery figure.
The most obvious nominee is John the Apostle, one of Christ’s inner circle of 12 and the namesake of the Gospel. But none of the 12 apostles were present at the crucifixion, so that crosses him off the list. Lazarus, resurrected by Christ, is also considered. He seems to have been present at the cited events and is referred to specifically, in the story of His death and resurrection, as “he whom Thou lovest.”
Mary Magdalene, Judas, Jesus’s brother James, or an unnamed disciple, possibly even a Roman or governmental official, have all been considered. There is even a school of thought that John is an interactive gospel, with the reader being the beloved disciple.

6  Simon Magus

05
 
“Simony” is the selling of church position or privilege. It is named for Simon Magus, or Simon the Magician, who makes only a brief appearance in the Bible, in Acts 8:9–24. Simon has since become synonymous with heretical thought, and religious exploitation.
He is presented as a powerful magician with a large following of in Samaria, who converts to Christianity and wishes to learn from apostles Peter and Phillip. When he sees the gifts of the Holy Spirit, including speaking in tongues and an ecstatic spiritual state, he offers the men money if they will give him the secret to passing these gifts to others. They are not amused.
Apocryphal texts reveal quite a bit more, like his alleged ability to levitate and even fly, emphasizing that he was something akin to a cult leader in his hometown. It is suggested that his conversion is more for economic purposes than spiritual, and he set himself up as a messianic figure himself, competing for the Jesus dollar with his own homespun theology.
He is thought by some to be a founder of Gnosticism, a patchwork of various religious systems that relied heavily on Judaic and Christian symbolism.

5  Onan

06
 
Not unlike Simon Magus, Onan’s brief appearance inspired a name for a particular action.
He was the second son of Abraham’s grandson Judah, the patriarch and namesake of one of the 12 tribes of Israel. His older brother, Er (yes, just “Er”) was “wicked in the sight of the Lord,” so God killed him. What he did to deserve such an execution remains a mystery.
Tradition at the time dictated that Er’s widow, Tamar, become Onan’s wife. Onan had to impregnate her to keep the lineage alive, but he was not as wild about the idea. Maybe it was the thought of impending fatherhood, or Tamar just wasn’t his type. So, taking matters into his own hands, he committed the first recorded act of coitus interruptus. Or, as Genesis 38:9 so poetically put it: “And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother’s wife, that he spilled it on the ground, lest that he should give seed to his brother.” God was displeased and slew Onan.
The whole tale gets even more sordid. Onan had a younger brother, Shelah. Customarily, he would have been next in line to impregnate Tamar, but Judah forbade it. Tamar, rather than graciously accepting forced spinsterhood, seduced Judah and (became pregnant) by the old man. Judah fathered twins Zerah and Perez, the latter of whom was listed by Matthew as an ancestor of Jesus’s earthly father Joseph...
Some have even suggested that Onan’s death warns that sex is meant only for purposes of reproduction, and not for pleasure.

4  Nicodemus

07
 
Nicodemus was a member of the Sanhedrin, a council of men who ruled on Jewish law and governance. He became a friend, follower, and intellectual foil for Jesus, whose egalitarian teachings often ran counter to the Sanhedrin’s rigid decrees. He was also a Pharisee, a leader within the Jewish community who toadied up to the Roman government at the time of Christ’s arrest and subsequent crucifixion.
He is mentioned three times in the New Testament, all in the Gospel of John. He subtly defends Jesus as the Pharisees discuss His impending arrest. Later, he helps prepare Jesus’s body for burial, indicating he had become an adherent to Christ and His teachings.
The first time he is mentioned, however, is in dialogue with Jesus, and these conversations reveal some of the most important aspects of Christian theology, such as the notion of being “born again” and the most famous reference to the divinity of Christ, John 3:16: “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
This detailed conversation explores the divide between the Old Covenant’s dogmatic and exclusive Jewish Law and the New Covenant’s spiritually inclusive concepts. But for a vital contributor to such an important passage of the New Testament, Nicodemus remains a mysterious figure. Some scholars have suggested he may be Nicodemus ben Gurion, a Talmudic figure of wealth and mystical power. Christian tradition suggest he was martyred, and he is venerated as a saint. His name has come to be synonymous with seekers of the truth and is used as a character in many works of biblically inspired fiction.

3  James The Just

08
 
He is considered, next to Paul and Peter, the most important apostolic figure in the Church’s history. The Book of Acts specifically names him the head of the Christian church in Jerusalem, and he is frequently cited, both scripturally and apocryphally, as being consulted by both Paul and Peter. So who is he?
Traditionally, he is thought of as Jesus’s brother (or, more precisely, His half-brother). Jesus is listed, in the Gospels, as having siblings, some younger than Him. One was named James.
But James was a common name, and there are several mentioned in the Bible. Two of the 12 disciples were named James, but both are listed as having different fathers than Jesus, and neither went on to become James the Just. James the son of Zebedee went on to be known as James the Great, and James the son of Alphaeus was called James the Less.
It is known that he was a contemporary of Jesus, although he seems to have had no real inner-circle status during Christ’s ministry. The apocryphal Gospel of Thomas says Christ Himself designated James to lead the movement upon His death. The Apostle Paul initially seems respectful, even subservient, to “James the Lord’s brother,” calling him a “pillar” of the movement, even though he was later to disagree with him on matters of doctrine.
Some, though, have suggested the “brother” designation was spiritual, rather than physical. St. Jerome, among others, suggested that the doctrine of perpetual virginity indicated James could be a cousin, which, given the tribal associations and clannishness of the Jewish community of the time, seems valid. Such a relationship would indicate a certain social proximity without necessarily being a true sibling.

2  Simon The Zealot

09
 
Of Christ’s 12 disciples, none are more mysterious than Simon the Zealot. His name was meant to differentiate him from Simon Peter and has come to symbolize, for some, that he was a member of a similarly named political movement that advocated Jewish defiance to Roman law. Some have speculated that he acted, within Christ’s inner circle, as a political adviser. His presence then indicated that Jesus had a revolutionary political agenda.
The truth is much less exciting. The “Zealot” movement did not take place until long after the time that Christ would have given Simon his sobriquet, and there has never been any serious evidence that Simon, despite the designation, was a political radical. The name, and the word upon which it is based, did not take on those aggressive undertones until the movement itself was in full swing. More than likely, Simon was given his name because of intense spiritual devotion, rather than any radical political stance.
Nothing else is known of him, at least not with any surety. The Catholic Encyclopedia mentions him as possibly being a brother or cousin of Jesus, with no real evidence. The Eastern Orthodox tradition says he developed his zeal when Jesus attended his wedding and changed water into wine. Some legends say he was martyred; the philosopher Justus Lipsius somehow got it into his head that he was sawed in half.

1  Og

10
 
Cited twice specifically, but alluded to frequently in general terms, the Nephilim were a race of violent giants that lived in the pre-Flood world at the same time as humanity. Were they, as some suggest, the offspring of demons and human women? Fallen angels themselves? Or simply the descendants of Seth mentioned in the Dead Sea scrolls, a tribe of cranky cases cursed by God for their rebelliousness? Regardless, they evolved and became known by other names, like the Raphaim, and frequently battled humans for land and power.
The most storied of them was Og, the King of Bashan. He was killed, along with his entire army, and his kingdom was ransacked. All of the survivors—men, women, and children—were put to death, and the strongest and most powerful line of Nephilim descendants was eliminated. Some Nephilim bloodlines continued to do battle with the Israelites, though they were becoming less powerful and dying out. One tribe, the Anakim, allied themselves with the human tribes in Philistia. Goliath was thought to have been one of the last few descendants of the Nephilim.
Goliath’s height is given in the earliest manuscripts as 275 centimeters (9′). That’s hardly as awe-inspiring as the creature laying in Og’s bed, which measured, according to Deuteronomy, 400 centimeters (13′ 6″). That’s basically Yao Ming sitting on Shaquille O’Neal’s shoulders.
Biblically, descendants of the Nephilim could not have survived the Flood, even though Og and other giants are post-Flood figures. Some biblical literalists have attributed their later existence to the descendants of Noah’s family hooking up, once again, with demons. Or, being fallen angels and not human, they did survive the flood.
Jewish tradition gets deeper into information about the Nephilim and their descendants, going against the grain of the biblical account. It tells of Og booking passage on the Ark by promising to act as a slave to Noah and his family. Other accounts have him hanging on to the side of the Ark and riding the flood out rodeo-style.

Meteorite is ‘hard drive’ from space ~ Researchers decode ancient recordings from asteroid ~ BBC

January 21, 2015 / / 0 Comments


Pallasite meteorite
The Esquel meteorite consists of gem-quality crystals embedded in metal.



Excert from bbc.com

Researchers have decoded ancient recordings from fragments of an asteroid dating back billions of years to the start of the Solar System. 

They found tiny "space magnets" in meteorites which retain a memory of the birth and death of the asteroid's core.
Like the data recorded on the surface of a computer hard drive, the magnetic signals written in the space rock reveal how Earth's own metallic core and magnetic field may one day die.

The work appears in Nature journal.

Using a giant X-ray microscope, called a synchrotron, the team was able to read the signals that formed more than four-and-a-half billion years ago, soon after the birth of the Solar System.

It's like a cosmic archaeological mission”
Dr James Bryson University of Cambridge
The meteorites are pieces of a parent asteroid that originally came from asteroid belt, between Mars and Jupiter.
They represents the left-over fragments of a planet that failed to form. The magnetic recording within it traps a signal of the precise moments when an iron-rich core formed in the asteroid as well as when it froze, killing its magnetic field.
The new picture of metallic core solidification in the asteroid provide clues about the magnetic field and iron-rich core of Earth.
Core values "Ideas about how the Earth's core evolved through [our planet's] history are really changing at the moment," lead researcher Dr Richard Harrison, from the University of Cambridge, told BBC News.
"We believe that Earth's magnetic field is linked to core solidification. Earth's solid inner core may have started to form at very interesting time in terms of the evolution of life on Earth.
"By studying an asteroid we get to see this in fast forward. We can see the start of core solidification in the magnetic records as well as its end, and start to think about how these processes work on Earth."

Magnetic fieldThe Earth's magnetic field will likely die off when the core completely freezes
The meteorites studied by the team originally fell to Earth in Argentina, and are composed of gem-quality crystals enclosed in a metallic matrix of iron and nickel. 

Tiny particles, smaller than one thousandth the width of a human hair, trapped within the metal have retained the magnetic signature of the parent asteroid from its birth in the early Solar System.

"We're taking ancient magnetic field measurements in nano-scale materials to the highest ever resolution in order to piece together the magnetic history of asteroids - it's like a cosmic archaeological mission," said Dr James Bryson, the paper's lead author. 

"Since asteroids are much smaller than Earth, they cooled much more quickly, so these processes occur on a shorter timescales, enabling us to study the whole process of core solidification."

Prof Wyn William, from the University of Edinburgh, who was not involved in the study, commented: "To be able to get a time stamp on these recordings, to get a cooling rate and the time of solidification, is fantastic. It's a very nice piece of work."

The key to the long-lived stability of the recording is the atomic-scale structure of the iron-nickel particles that grew slowly in the asteroid core and survived in the meteorites. 

Making a final comment on the results, Dr Harrison said: "In our meteorites we've been able to capture both the beginning and end of core freezing, which will help us understand how these processes affected the Earth in the past and provide a possible glimpse of what might happen in the future."

Top 6 tips for using ordinary binoculars for stargazing

January 1, 2015 / / 0 Comments




Excerpt from earthsky.org


Admit it.  You’ve probably got a pair of binoculars lying around your house somewhere. They may be perfect – that’s right, perfect – for beginning stargazing. Follow the links below to learn more about the best deal around for people who want to get acquainted with the night sky: a pair of ordinary binoculars.
1. Binoculars are a better place to start than telescopes
2. Start with a small, easy-to-use size
3. First, view the moon with binoculars.
4. Move on to viewing planets with binoculars.
5. Use your binoculars to explore inside our Milky Way.
6. Use your binoculars to peer beyond the Milky Way.

1. Binoculars are a better place to start than telescopes. The fact is that most people who think they want to buy a telescope would be better off using binoculars for a year or so instead.  That’s because first-time telescope users often find themselves completely confused – and ultimately put off – by the dual tasks of learning the use a complicated piece of equipment (the ‘scope) while at the same time learning to navigate an unknown realm (the night sky).
Beginning stargazers often find that an ordinary pair of binoculars – available from any discount store – can give them the experience they’re looking for.  After all, in astronomy, magnification and light-gathering power let you see more of what’s up there.  Even a moderate form of power, like those provided by a pair of 7×50 binoculars, reveals 7 times as much information as the unaided eye can see.

You also need to know where to look. Many people start with a planisphere as they begin their journey making friends with the stars. You can purchase a planisphere at the EarthSky store. Also consider our Astronomy Kit, which has a booklet on what you can see with your binoculars.

2. Start with a small, easy-to-use size.  Don’t buy a huge pair of binoculars to start with! Unless you mount them on a tripod, they’ll shake and make your view of the heavens shakey, too. The video above – from ExpertVillage – does a good job summing up what you want. And in case you don’t want to watch the video, the answer is that 7X50 binoculars are optimum for budding astronomers.  You can see a lot, and you can hold them steadily enough that jitters don’t spoil your view of the sky.  Plus they’re very useful for daylight pursuits, like birdwatching. If 7X50s are too big for you – or if you want binoculars for a child – try 7X35s.

3. First, view the moon with binoculars. When you start to stargaze, you’ll want to watch the phase of the moon carefully. If you want to see deep-sky objects inside our Milky Way galaxy – or outside the galaxy – you’ll want to avoid the moon. But the moon itself is a perfect target for beginning astronomers, armed with binoculars. Hint: the best time to observe the moon is in twilight. Then the glare of the moon is not so great, and you’ll see more detail.

You’ll want to start your moon-gazing when the moon is just past new – and visible as a waxing crescent in the western sky after sunset. At such times, you’ll have a beautiful view of earthshine on the moon.  This eerie glow on the moon’s darkened portion is really light reflected from Earth onto the moon’s surface.  Be sure to turn your binoculars on the moon at these times to enhance the view. 
Each month, as the moon goes through its regular phases, you can see the line of sunrise and sunset on the moon progress across the moon’s face. That’s just the line between light and dark on the moon. This line between the day and night sides of the moon is called the terminator line.  The best place to look at the moon from Earth – using your binoculars – is along the terminator line. The sun angle is very low in this twilight zone, just as the sun is low in our sky around earthly twilight.  So, along the terminator on the moon, lunar features cast long shadows in sharp relief.

You can also look in on the gray blotches on the moon called maria, named when early astronomers thought these lunar features were seas.  The maria are not seas, of course, and instead they’re now thought to have formed 3.5 billion years ago when asteroid-sized rocks hit the moon so hard that lava percolated up through cracks in the lunar crust and flooded the impact basins. These lava plains cooled and eventually formed the gray seas we see today.

The white highlands, nestled between the maria, are older terrain pockmarked by thousands of craters that formed over the eons. Some of the larger craters are visible in binoculars. One of them, Tycho, at the six o’clock position on the moon, emanates long swatches of white rays for hundreds of miles over the adjacent highlands. This is material kicked out during the Tycho impact 2.5 million years ago.

4. Move on to viewing planets with binoculars. Here’s the deal about planets.  They move around, apart from the fixed stars.  They are wanderers, right?

You can use our EarthSky Tonight page to locate planets visible around now.  Notice if any planets are mentioned in the calendar on the Tonight page, and if so click on that day’s link.  On our Tonight page, we feature planets on days when they’re easily identifiable for some reason – for example, when a planet is near the moon.  So our Tonight page calendar can help you come to know the planets, and, as you’re learning to identify them, keep your binoculars very handy. Binoculars will enhance your view of a planet near the moon, for example, or two planets near each other in the twilight sky. They add a lot to the fun!

Below, you’ll find some more simple ideas on how to view planets with your binoculars.

Mercury and Venus. These are both inner planets.  They orbit the sun closer than Earth’s orbit.  And for that reason, both Mercury and Venus show phases as seen from Earth at certain times in their orbit – a few days before or after the planet passes between the sun and Earth.  At such times,  turn your binoculars on Mercury or Venus. Good optical quality helps here, but you should be able to see them in a crescent phase. Tip: Venus is so bright that its glare will overwhelm the view. Try looking in twilight instead of true darkness.

Mars. Mars – the Red Planet – really does look red, and using binoculars will intensify the color of this object (or of any colored star). Mars also moves rapidly in front of the stars, and it’s fun to aim your binoculars in its direction when it’s passing near another bright star or planet.

Jupiter. Now on to the real action!  Jupiter is a great binocular target, even for beginners.   If you are sure to hold your binoculars steadily as you peer at this bright planet,  you should see four bright points of light near it.  These are the Galilean Satellites – four moons gleaned through one of the first telescopes ever made, by the Italian astronomer Galileo. Note how their relative positions change from night to night as each moon moves around Jupiter in its own orbit.

Saturn.Although a small telescope is needed to see Saturn’s rings, you can use your binoculars to see Saturn’s beautiful golden color.  Experienced observers sometimes glimpse Saturn’s largest moon Titan with binoculars.  Also, good-quality high-powered binoculars – mounted on a tripod – will show you that Saturn is not round.  The rings give it an elliptical shape.

Uranus and Neptune. Some planets are squarely binocular and telescope targets. If you’re armed with a finder chart, two of them, Uranus and Neptune, are easy to spot in binoculars. Uranus might even look greenish, thanks to methane in the planet’s atmosphere. Once a year, Uranus is barely bright enough to glimpse with the unaided eye . . . use binoculars to find it first. Distant Neptune will always look like a star, even though it has an atmosphere practically identical to Uranus.

There are still other denizens of the solar system you can capture through binocs. Look for the occasional comet, which appears as a fuzzy blob of light. Then there are the asteroids – fully 12 of them can be followed with binoculars when they are at their brightest. Because an asteroid looks star-like, the secret to confirming its presence is to sketch a star field through which it’s passing. Do this over subsequent nights; the star that changes position relative to the others is our solar system interloper.

5. Use your binoculars to explore inside our Milky Way.  Binoculars can introduce you to many members of our home galaxy. A good place to start is with star clusters that are close to Earth. They cover a larger area of the sky than other, more distant clusters usually glimpsed through a telescope.

Beginning each autumn and into the spring, look for a tiny dipper-like cluster of stars called the Pleiades.  The cluster – sometimes also called the Seven Sisters – is noticeable for being small yet distinctively dipper-like. While most people say they see only six stars here with the unaided eye, binoculars reveal many more stars, plus a dainty chain of stars extending off to one side. The Pleiades star cluster is looks big and distinctive because it’s relatively close – about 400 light years from Earth. This dipper-shaped cluster is a true cluster of stars in space.  Its members were born around the same time and are still bound by gravity.  These stars are very young, on the order of 20 million years old, in contrast to the roughly five billion years for our sun.

Stars in a cluster all formed from the same gas cloud. You can also see what the Pleiades might have like in a primordial state, by shifting your gaze to the prominent constellation Orion the Hunter. Look for Orion’s sword stars, just below his prominent belt stars. If the night is crisp and clear, and you’re away from urban streetlight glare, unaided eyes will show that the sword isn’t entirely composed of stars. Binoculars show a steady patch of glowing gas where, right at this moment, a star cluster is being born. It’s called the Orion Nebula. A summertime counterpart is the Lagoon Nebula, in Sagittarius the Archer.

With star factories like the Orion Nebula, we aren’t really seeing the young stars themselves. They are buried deep within the nebula, bathing the gas cloud with ultraviolet radiation and making it glow. In a few tens of thousands of years, stellar winds from these young, energetic stars will blow away their gaseous cocoons to reveal a newly minted star cluster.

Scan along the Milky Way to see still more sights that hint at our home galaxy’s complexity. First, there’s the Milky Way glow itself; just a casual glance through binoculars will reveal that it is still more stars we can’t resolve with our eyes . . . hundreds of thousands of them. Periodically, while scanning, you might sweep past what appears to be blob-like, black voids in the stellar sheen. These are dark, non-glowing pockets of gas and dust that we see silhouetted against the stellar backdrop. This is the stuff of future star and solar systems, just waiting around to coalesce into new suns.

6. Use your binoculars to view beyond the Milky Way.  Let’s leap out of our galaxy for the final stop in our binocular tour. Throughout fall and winter, she reigns high in the sky during northern hemisphere autumns and winters: Andromeda the Maiden. Centered in the star pattern is an oval patch of light, readily visible to the unaided eye away from urban lights. Binoculars will show it even better.

It’s a whole other galaxy like our own, shining across the vastness of intergalactic space. Light from the Andromeda Galaxy has traveled so far that it’s taken more than 2 million years to reach us.
Two smaller companions visible through binoculars on a dark, transparent night are the Andromeda Galaxy’s version of our Milky Way’s Magellanic Clouds. These small, orbiting, irregularly-shaped galaxies that will eventually be torn apart by their parent galaxy’s gravity.

Such sights, from lunar wastelands to the glow of a nearby island universe, are all within reach of a pair of handheld optics, really small telescopes in their own right: your binoculars.

John Shibley wrote the original draft of this article, years ago, and we’ve been expanding it and updating it ever since. Thanks, John!
Bottom line: For beginning stargazers, there’s no better tool than an ordinary pair of binoculars. This post tells you why, explains what size to get, and gives you a rundown on some of the coolest binoculars sights out there: the moon, the planets, inside the Milky Way, and beyond. Have fun!

Carl Sagan Narrates A Hopeful View Of The Future In ‘Wanderers,’ A Short About Space Exploration

November 30, 2014 / / 0 Comments






Excerpt from
uproxx.com
With Interstellar blowing minds in theaters, interest in space exploration is heightened with the public. Not that we ever stopped thinking about it, we just put it on the back burner and forgot about it for far too long. This short film from Erik Wernquist is hoping we start to remember it.

Utilizing Carl Sagan’s Pale Blue Dot for narration, Wernquist creates a stunning trip through the galaxy to paint a picture of a future where we venture out. It’s a hell of a ride with no shortage of beauty. From the video:
Wanderers is a vision of humanity’s expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available.
Without any apparent story, other than what you may fill in by yourself, the idea with the film is primarily to show a glimpse of the fantastic and beautiful nature that surrounds us on our neighboring worlds – and above all, how it might appear to us if we were there.
Sagan’s word really help to push it past just a beautiful visual piece. It’s a good introduction, along with the original Cosmos, into how he could describe these events in a way that established some wonder. From Sploid:
Your own life, or your band’s, or even your species’ might be owed to a restless few—drawn, by a craving they can hardly articulate or understand, to undiscovered lands and new worlds.

The India Space Research Organization unveils its first pictures of the red planet.

India's first Mars probe has captured its first photos, revealing an early glimpse of the surface and atmosphere of the Red Planet.
The Indian Space Research Organisation (ISRO) unveiled the first photos of Mars from its Mangalyaan spacecraft via Facebook and Twitter on Wednesday and Thursday (Sept. 24-25), just a day or so after the probe made it to the Red Planet.

Mars surface

"The view is nice up here," ISRO officials tweeted about one of the images, which shows a heavily cratered portion of the Red Planet's surface.

Another photo depicts the curving, orange-brown limb of Mars against the blackness of space.

"A shot of Martian atmosphere. I'm getting better at it. No pressure," ISRO officials tweeted about that one.

Mangalyaan, whose name means "Mars craft" in Sanskrit, arrived at the Red Planet on Tuesday night (Sept. 23), making India's space agency just the fourth entity — after the United States, the Soviet Union and the European Space Agency — to successfully place a probe in orbit around Mars.

Mangalyaan is the centerpiece of India's $74 million Mars Orbiter Mission (MOM), which ISRO officials have described as primarily a technology demonstration. The spacecraft carries a camera and four scientific instruments that it will use to study the Martian surface and atmosphere during the course of a mission expected to last six to 10 months. 

MOM reached Mars close on the heels of NASA's MAVEN (Mars Atmosphere and Volatile Evolution) probe, which was captured by the Red Planet's gravity on Sunday (Sept. 21). The $671 million MAVEN mission aims to help scientists determine what happened to Mars' atmosphere, which was once relatively thick but is now just 1 percent as dense as that of Earth.

MAVEN has also taken its first images of Mars from orbit; NASA released a few false-color views of the planet's atmosphere on Wednesday.

Mars orbit now hosts five operational spacecraft; NASA's Mars Odyssey probe and Mars Reconnaissance Orbiter, as well as Europe's Mars Express craft, share space with MAVEN and Mangalyaan. And two rovers (NASA's Opportunity and Curiosity) are actively exploriong the planet's surface.
